I'd add to this topic that weapons training or tactical skill training can help address some of these issues too in a real world event.
Many sworn LE officers, federal agents & other armed professionals(bodyguards, PSCs, security officers, etc) train to make tactical reloads or transition to other fully loaded weapons in critical incidents.
These factors also show why a 15/16/18 shot duty pistol is far better than a 5 or 6 shot DA revolver in 2011.
To say "6 for sure" or "wheel guns are real guns" may sound macho or cool but in the real world, there is honestly little or no practical reason not to use a semi auto pistol or pistols on duty. With little effort you get nearly 3 times the firepower.
